Overview of this book

This book is an incremental guide that will help you learn and use the advanced features of the Selenium toolset including the WebDriver API in various situations to build a reliable test automation. You start off by setting up the test development environment and gain tips on the advanced locater strategy and the effective use of the Selenium WebDriver API. After that, the use of design patterns such as data - driven tests and PageFactory are demonstrated. You will then be familiarised with extending Selenium WebDriver API by implementing custom tasks and setting up your own distributed environment to run tests in parallel for cross-browser testing. Finally, we give you some tips on integrating Selenium WebDriver with other popular tools and testing mobile applications.

Sometimes, third-party controls, images, and media content also cause degradation in the performance. Using Selenium WebDriver and various other tools together, we can measure the performance and eliminate the weaker content.

Navigation Timing is a W3C Standard JavaScript API to measure performance on the Web.
